SELF STOVE-LIGHTER 0R PILOT-LIGHT.

Specification of Letters Patent. Patented June 12, 1917.

I application filed December 10, 1915. Serial No. 66,101.

[0 all whom it may concern:

Be it known that I, CHARLES L. GISLER, a citizen of the United States, residing at Sistersville, in the county of Tyler, State of West Virginia, have invented a new and useful Self Stove-Lighter or Pilot-Light; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved pilot light tube and spreader thereon, for use in connection with incandescent lights, gas jets and gas burners.

A further object of the invention is to provide a spreader in order to spread the pilot light over the upper end of the mantle of the Welsbach lamp, or to spread the pilot light over one of the perforations of the gas burner, whether it forms a part of a gas stove or any other suitable apparatus, in order to insure the lighting of the gas.

Another object of the invention is to pro vide an extensible tube between the spreading pilot light and where the tube receives its gas from the main pipe, below or beyond the controlling valve, so that the tube may be adjusted to fit diiferent lengths of burners.

In practical fields the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combinations of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a view in elevation of the pilot light tube applied to a gas jet.

Fig. 2 is a view in elevation showing the pilot light tube with its spreader applied to a Welsbach burner. v

Fig. 3 is an enlarged sectional view through a portion of the structure of Fig. 2.

Fig. 4 is a plan view of the pilot light tube as applied to a burner of a gas stove.

Fig. 5 is a sectional view on line 55 of Fig. 4.

Fig. ,6 is a sectional view on line 6-6 of Fig. 5.

Referring more particularly to the drawings,

1 designates the gas jet tube having the usual burner tube 2 and tip 3. The gas jet tube 1 is connected in the usual manner at 4 pipe 6. form of valve 7, the opening of which turns to the valve casing 5 which, in turn, is con nected 1n the usual manner to the gas supply The caslng 5 has a conventional on the gas, so that it may be lighted at the tip 3. The casing 5 has an extension 8, into which the pilot light tube 9 is threaded. The extension 8 has a passage of communication, as shown at 10, with the interior of the casing 5 and the supply pipe 6. A screw 11 is threaded into the extension 8, at right angles to the pilot light tube 9, and by adjusting said screw one way or the other, it will play across the passage 12 of the pilot light tube, where said passage communicates with the passage 10 in the extension 8, in order to control the gas in its flow through the pilot light tube, in order that only a small quantity of gas is allowed to escape at the outlet end of the pilot light tube, as shown at 13. This small quantity of gas is designed to be lighted at 13, so that when the gas through the gas jet tube 1 is turned on by opening the valve 7, the full supply of gas at the tip will automatically become lighted. The pilot light tube 9 consists of two sections 14 and 15 telescopically united, which sections have groove and rib connections 16 and 17, to prevent the sections from turning relative to each other, and to hold the right-angled extending part 18 in its proper position, so that the end 13 remains adjacent the tip 3 of the jet. In Figs. 2 and 3, the section 15 of the pilot light tube terminates in a pilot light spreader 19, which consists of a hollow casing 20 having its upper wall convexed, and its lower wall'is convexed and concaved, and is provided with perforations 21, which are extremely small, and from each of which when the gas is lighted a very small flame emanates. These flames spread over the upper end of the gas mantle of the Welsbach lamp, so that the gas may instantly become lighted. In Fig. 4 the spreading pilot light spreads over one of the perforations of the gas burner of the gas stove, so that as the gas reaches the burnerit becomes lighted. In Figs. 2, 3, 4 and 5, the pilot light tube consists of two sections, as shown in Fig. 1.

The invention having been set forth, what is claimed as new and useful is 1. In combination with a gas burner, a pilot tube having one end extending upwardly terminating in a spreading hollow substantially semi-spherical pilot light cas ing having its under wall concaved and provided with perforations and arching over the gas outlet of said burner to ignite the gas from the burner.

2. In combination with a gas burner a pilot tube having an extensible section having one end extending upwardly, said upwardly extending portion terminating in a spreading hollow substantially semi-spherical pilot light casing having its under Wall concaved upwardly, said concaved wall provided with perforations and arching over the gas outlet of the burner to ignite the gas m he burn r, and. mea for holding said extensible section, whereby said upwardly extending portion may be maintained in such parallelism with the burner, as to hold the pilot light casing over the ut et f th bu n In testimony whereof I have signedmy name to this specification.
